I see the copy of the ROM is on mdfs.net along with an advert, I had a quick search for more info but not come up with anything yet, will keep looking. So my questions are:

1) Does anyone know where the install/ops manual for 6502 BASIC V is?2) I assume any BASIC V programming manual for Archie/RISC OS can be followed as long as you ignore bits about windows and embedded ARM assembly?
